Product details
Overview
JANTX1N4115D-1 from Microsemi is a 500 mW, 22 V, 1% tolerance Zener diode in DO-35 glass package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4115D-1 datasheet, JANTX1N4115D-1 pinout, JANTX1N4115D-1 application, or JANTX1N4115D-1 equivalent, key selection factors include its 1% Zener voltage tolerance, 150 Ω dynamic impedance at 250 mA, 0.01 µA reverse leakage at 17.6 V, radiation-hardened construction, and hermetic glass axial-leaded packaging.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded junctions for stable breakdown behavior across temperature and radiation environments. It delivers 22 V regulation at 250 mA test current (IZT), with dynamic impedance of 150 Ω and temperature coefficient of +0.090 %/°C.
Designed for high-reliability analog references and overvoltage protection, it features low noise density (1 µV/√Hz typical at lower voltages), minimal capacitance (~4 pF), and ESD immunity per MIL-STD-750 Method 1020 - all validated under military-grade screening up to JANTX level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 22.0 V ±1% at 250 mA - ensures tight reference stability for precision biasing and feedback loops. |
| Power Dissipation | 500 mW at 25 °C - supports continuous regulation in compact, unheatsinked designs with linear derating above 50 °C. |
| Dynamic Impedance ZZT | 150 Ω at IZT = 250 mA - limits output voltage variation under load transients in regulated supplies. |
| Reverse Leakage IR | 0.01 µA at VR = 17.6 V - minimizes quiescent current loss in low-power standby circuits. |
| Temp. Coefficient αVZ | +0.090 %/°C - enables predictable drift compensation in wide-temperature-range instrumentation. |
| Noise Density ND | 1 µV/√Hz (typical) - critical for low-noise analog references in signal conditioning and ADC reference buffers. |
| Junction Temp. Range | –65 °C to +175 °C - supports operation in extreme environmental conditions including space and engine bays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4115US-1 | Same 22 V, 1% spec but in DO-213AA surface-mount package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when automated assembly and board space constraints outweigh manual serviceability needs. |
| JAN1N4115D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX). | Lacks JANTX-level burn-in and extended temperature testing; not approved for mission-critical flight hardware. | Acceptable for ground-test equipment or non-flight subsystems where cost sensitivity outweighs full JANTX reliability. |
Compared with JANTX1N4115D-1, the 1N4115US-1 enables miniaturized SMT layouts but sacrifices mechanical robustness and repairability, while JAN1N4115D-1 reduces procurement cost and lead time at the expense of verified high-reliability performance under sustained stress.

FAQ
What is the Zener voltage tolerance of JANTX1N4115D-1?
JANTX1N4115D-1 has a nominal Zener voltage of 22.0 V with ±1% tolerance, confirmed per the "D" suffix in its nomenclature and verified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tight tolerance enables direct use in precision reference circuits without post-manufacture calibration.
Is JANTX1N4115D-1 RoHS compliant?
No, JANTX1N4115D-1 is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is absent in JANTX1N4115D-1. RoHS-compliant versions are available only in commercial-grade variants, not JANTX-level devices.
What is the maximum reverse leakage current for JANTX1N4115D-1?
The maximum reverse leakage current (IR) for JANTX1N4115D-1 is 0.01 µA at VR = 17.6 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This ultra-low leakage supports energy-efficient operation in battery-backed and low-quiescent-current systems.
Does JANTX1N4115D-1 require heatsinking in standard operation?
No, JANTX1N4115D-1 does not require external heatsinking at ambient temperatures ≤50 °C. Its 500 mW power rating is rated at 25 °C lead temperature and linearly derates to zero at 175 °C, with RθJL = 250 °C/W - sufficient for typical axial-lead mounting on FR4 boards with 3/8″ lead length.
How is polarity marked on JANTX1N4115D-1?
JANTX1N4115D-1 uses a cathode band marking per the Mechanical and Packaging section on page 2 of T4-LDS-0245-2 Rev. 1. The banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation - incorrect polarity results in forward conduction at ~1.1 V.
